LUBRICATOR FOR ECCENTRICS.

Specification of Letters Patent.

Patented April 21, 1908.

Application filed August 28, 1907. Serial No. 390,538.

To all whom it may concern.'

Be it known that I, CLYvE DoLPHrN HELM, a citizen of the United States,residing at Fort Worth, in the county of Tarrant and State of Texas,have invented a new and useful Lubricator for Eccentrics, of which thefollowing is a specification.

This invention relates to eccentrics and more particularly to means forapplying a lubricant to the eccentric and its associated parts.

The objectof the invention is to provide an eccentric including asectional strap one section of which is formed with an interior chamberor reservoir adapted to contain a quantity of oil or other lubricantwhich is distributed over the surface of the eccentric when the latteris rotated Vthereby to prevent 4 undue friction between the parts.

A further object is to provide means fo'r supplying oil to thelubricating chamber or reservoir and means for regulating the 'dischargeof lubricant from said chamber.

A still further object of the invention is to generally improve thisclass of devices so as to increase their utility, durability andeiliciency. l

Further objects and advantages will appear in the following description,it being understood that various changes in form, proportions and minordetails of construction may be resorted to within the scope of the apended claims.

In t e accompanying drawings forming a -part of this specification:Figure 1 is a side elevation of an eccentric provided with a lubricatingdeviceconstructed in accordance with my invention. Fig. 2 is a verticalsectional view taken on the line 2 2 of Fig. 1.

Similar numerals of reference indicate corresponding parts in all of thefigures of the drawings.

The improved lubricating device may be applied to the eccentrics ofgas-engines, steam engines or other machinery and by way of illustrationis shown in connection with an eccentric of the ordinary constructionin' which 5 designates the o erating shaft and 6 the eccentric plateordisk).

Surrounding; the disk or eccentric 6 is a strap preferably formed in twosections 7 and 8, each provided with laterally extending lugs 9 havingperforations formed therein for the receptlon of bolts or similarfastening devices 10 whereby the sections of the strap may be clamped inposition on the disk 6.

One of the sections 8 is secured to or formed integral with theeccentric rod 11 while the opposite section is provided with a lateralenlargement 12 having an interior chamber or reservoir 13 formed thereinand adapted to contain a quantity of oil or other lubricant, as shown.

The outer curved wall of the enlargement 12 is provided with an opening14 through which oil or other lubricant is introduced into the reservoir13, the walls of said open ing being threaded for engagement with thecorrespondingly threaded walls of a cap or plug 15 which latter servesto normally close the reservoir and thus prevent the escape oflubricant. A i

The inner faces of the sections 7 and 8 are formed with acircumferential groove 16 adapted to receive the peripheral edge of thedisk 6 and formed in the wall of the groove 16 and communicating withthe reservoir 13 is a threaded opening 17, there being a similar opening18 formed in the outer curved wall of the enlargement l2 and disposed inalinement with the opening 17 for the reception of a feed tube 19.

The lower end of the feed tube 19 is reduced at 20 and provided withterminal t threads 21 for engagement with the threads of the' opening 17when the tube is placed in position on the stra section 7. The exteriorwalls of the tu e 19 at the upper end thereof are perfectly smooth andunobstructed for engagement with the correspondingly smooth interiorwalls of the opening 18, there being a rectangular head 22 formed on theupper end of the tube so that the latter may be conveniently graspedwith a wrench or other suitable tool when ositioning the ytube withinthe oil recelving reservoir. The interior walls of the tube at the upperend thereof are threaded at 23` for engagement with the threadedexterior walls of a cap or feeding device 24, the latter being providedwith a plurality of feed apertures 25 adapted to correspondinglyregister with corresponding feedl apertures 26 formed in the tube 19thereby to permit the oil or other lubricant in the reservoir to flowthrough the tube and lubricate the eccentric and its associated parts. n

Arranged within the tube 19 and cap 24 is a quantity of felt, cotton,vegetable ber or other absorbent material 27 which becomes saturatedwith oil from the reservoir 13 and which serves to uniformly distributethe same over the peripheral edge of the eccentric as the latter isrotated. It Will thus be seen that by rotating the cap 24 Witha Wrenchor other suitable tool the Width of the openings 26 may be varied atwill thereby to regulate the quantity of oil supplied through the tubeto the eccentric.

A Washer or gasket 28 is preferably interposed between the head 22 andthe adjacent curved face of the enlargement 12 in order to assist inpreventing leakage.

The device is comparatively simple in construction and thoroughlyefficient in operation and may be manufactured and placed on the marketat a comparatively small cost.

Having thus described the invention what is claimed is:

1. The combination With an eccentric, of a strap surrounding theeccentric and provided with a reservoir adapted to contain a lubricant,an open ended feed tube extending transversely through the reservoir,and having its inner end arranged to discharge the lubricant on theeccentric and means operating Within the feed tube and coacting with thelatter for regulating the discharge of lubricant from said reservoirsaid regulating means forming a closure for the outer end of the feedtube.

2. The combination with an eccentric, of a strap surrounding theeccentric and provided with a lateral enlargement having a reservoirformed therein and adapted to contain a lubricant, an open ended feedtube extending transversely through the reservoir and having its innerend disposed at the periphery of the eccentric, said feed tube beingprovided Witha plurality of apertures communicating With the interior ofthe reservoir, and a ca operating Within the feed tube and provide Withcorresponding apertures adapted to register with the apertures in thetube for regulating the discharge of lubricant from the reservoir saidcap forming a closure for the open end of the feed tube.

3. The combination with an eccentric, of a strap surrounding theeccentric and provided with a lateral enlargement having a reservoirformed therein and adapted to receive a lubricant, one Wall of saidenlargement being provided with a threaded opening, an open ended feedtube extending transversely through the reservoir and having its innerend disposed at the peri hery of the eccentric and its exterior Wallsthreaded for engagement With the Walls of the opening, there being feedapertures formed in the tube and communicating With the interior of thereservoir, and a cap Working within the tube and provided withcorresponding apertures adapted to register with the a )ertures in thetube for regulating the flow of lubricant from the reservoir, said capforming a closure for the outer end of the feed tube.

4. The combination with an eccentric, of a strap surrounding theeccentric and provided with a lateral enlargement having a reservoirformed therein andy adapted to contain a lubricant7 an open ended feedtube extending transversely through the reservoir and having its innerend disposed at said eccentric and its interior Walls threaded andprovided with a plurality of feed apertures, absorbent material dis osedWithin the tube, and a cap forming a c osure for the outer end of theytube and having its exterior walls threaded for engagement with theinterior threaded walls of the tube, said cap being provided Withapertures adapted to register with the apertures in the tube forregulating theI discharge of lubricant from the reservoir.

5. The combination with an eccentric, ol' a strap surrounding theeccentric and provided with a circumferential groove, said strap beingformed in sections one of which is provided With a lateral enlargementhaving a reservoir formed therein and adapted to contain a lubricant,the walls of said reservoir being provided with alined openings one olwhich is threaded and the other provided With a smooth bore, a feed tubehaving one end thereof reduced and thremled for engagement With thethreaded walls of an adjacent opening and its opposite end extendingthrough the other opening and provided With an angular head, theinterior walls of said tube being threaded and having feed aperturesformed therein and communicating with the reservoir, a cap having anangular head and provided with exterior threads ada ted to engage theinterior threads ofthe feecljtube, said` cap being formed with aperturesadapted to register with the apertures` in the tube for regulating thedischarge of fluid from the reservoir, and absorbent inaterial arrangedWithin the tube and cap respectively, and bearing against the eccentricat the circumferential groove.
